登录流程

1）容器启动(MySecurityMetadataSource：loadResourceDefine加载系统资源与权限列表)

 2）用户发出请求

 3）过滤器拦截(MySecurityFilter:doFilter)

 4）取得请求资源所需权限(MySecurityMetadataSource:getAttributes)

 5）匹配用户拥有权限和请求权限(MyAccessDecisionManager:decide)，如果用户没有相应的权限，

执行第6步，否则执行第7步。

 6）登录

 7）验证并授权(MyUserDetailServiceImpl:loadUserByUsername)

1、web.xml中加入过滤器

  1. <!-- SpringSecurity 核心过滤器配置 -->
  2. <filter>
  3. <filter-name>springSecurityFilterChain</filter-name>
  4. <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  5. </filter>
  6. <filter-mapping>
  7. <filter-name>springSecurityFilterChain</filter-name>
  8. <url-pattern>/*</url-pattern>
  9. </filter-mapping>
<!-- SpringSecurity 核心过滤器配置 -->

<filter>

    <filter-name>springSecurityFilterChain</filter-name>

    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>

</filter>

<filter-mapping>

    <filter-name>springSecurityFilterChain</filter-name>

    <url-pattern>/*</url-pattern>

</filter-mapping>

2、新建spring-security.xml文件

  1. <?xml version="1.0" encoding="UTF-8"?>
